Today’s LiveWire Spotlight addresses PRC-026-1 Draft 2 – the final standard to be developed under Project 2010-13 “Relay Loadability”. When it takes effect, PRC-026-1 will govern the performance of load responsive relays protecting generators, transmission lines, and transformers during stable and unstable power swings.

The second draft of PRC-026-1 and its supporting documentation have been posted on the NERC web site for industry stakeholder review and concurrent ballot. Clients have until October 6, 2014 to submit comments and vote on the standard.
